How do you force the update?
I found this on another forum this morning when I was trying to troubleshoot it. Instead of changing the clock ahead a year, I had to do it for just a month because it would revert back to the current year. I couldn't get it to work past the reboot option, but you may have better luck with it.
[ method I ] Check for updates
1. From the Home screen, Press Menu key.
2. Tap Settings and scroll down the screen
3. Tap About Phone and tap System software updates
4. On the System software update screen, tap Check now.
5. If any software update message shows up, please follow the on-screen instruction.
[ method II ] Reconnecting to the Google server.
1. Open up your phone's dialer.
2. Key in *#*#2432546#*#*
3. If any software update message shows up, please follow the on-screen instruction
[ method III ] Force phone to check for update.
Please manually change the date on your phone to one year from today. This will trigger an automatic check in with the update servers and you will get the appropriate update.
1. Menu > Settings > Date and Time
2. Un-check Automatic to prevent the date and time from automatically updating
3. Change the date to one year from today (under Set Date)
4. Go back to the main settings and select About Phone > Check For Update and follow the prompts
Got the info
here. Good luck.
